SPECIFICATION forming part of Letters Patent No. 387,614, dated August7, 1888.

Application tiled Aprill, 1888. Serial No. 269,038.

To all whom it may concern.-

Be it known that I, J osnrrr GARDONA, a citizen of the United States,residing in the city of Chicago, in the county of Cook and State ofIllinois, have invented a new and useful Automat-ic Ti me-Indicator, inwhich the pressure of water or other liquid is used to mark time by theelevation and depression of the liquid. 1 attain this object by means ofthe mechanism illustrated in the accompanying drawings, in which- Figure1 is a'front viewol' the device in proper position. Fig. 2 is a verticalsection of the entire device as shown attached to a building. Fig. 3 isa sectional view of the revolving fan.

Similar letters refer to similar parts through out the drawings.

I place a vessel, A, filled with water or other liquid, in a position tosuit my purpose on the inside of any building or wherever it may bedesired to be placed. Into the vessel A is inserted the pump B, operatedby means of an ordinary revolving fan, C, placed outside of thebuilding, or where it is exposed to currents of air. The fan Chas on itsperimeter, at one end, 8, acog or gear wheel, which engages with thegear-wheel m on a horizontal shaft, a, on the opposite end of which isabevel gear-wheel, c, which engages with a similar wheel on the verticalshaft or rod (1, which operates the pump l3. By means of the pump B theliquid in the vessel A is raised through the tube a and discharges intothe reservoir D. A. waste pipe or overflow, m, with its month near thetop of the reservoir, is used to carry the surplus of the liquid backinto the vessel A. At the bottom of the reservoir I) is placed a faucet,h, properly gaged, which acts or serves as a feeder by discharging intoa receiving vessel or trough, Z), which is also supplied with anoverflow-pipe, g, which discharges into the (No model.)

waste-pipe 00, above described. From the receiving-vessel b the liquid,having at this point a constant and even pressure, is again dischargedby the faucet O, which serves as a regulator by limiting the quantitydischarged per minute or hour into the dial-box E, Fig. 1, which has atransparent face, and has marked thereon at regular spaces on both sidesof the dialplate from the bottom upward the hours 1 to 12 and thehalf-hours and minutes by means of graduated diagonal linesas, forinstance, when the liquid rises to the numeral 1 and passes beyond itthe graduated diagonal. line running from the figure 1 on the one sideof the dial-plate to figure 2 on the other side or end will indicate theperiod of time between the hours 1 and 2, and this is repeated until theliquid rises to 12, when the dial-box is automatically emptied by thesiphon Zt,Wl]lCh discharges into the waste-pipers the liquid returningto the vessel A. This process is repeated indefinitely. The dial-box isfilled and discharged every twelve hours. 7

I am aware that the measurement of time by means of water or liquids hasbeen known for centuries, and I do not claim it as my invention; but

What I do claim as new, and desire to secure by Letters Patent, is

As an automatic time-indicator, the combination of the revolving fan C,the pump 13, the gear-wheels m, shaft a, bcvcl gear-wheels 0, verticalshaft d, the vessel A, the tube a, reservoir D, the waste or overflowpipe a, the discharging faucotlz, rcccivi ng vessel or trough b, thegaged feeding-faucet 0, the dial-box E, and siphon u, as and for thepurpose above set forth.

JOSEPH CARDONA.
